What parameters would you consider a super ideal cut diamond?

I'm trying to evaluate some JA True Hearts diamonds but want to make sure they fall into stricter criteria.

So super ideals are more than just angles, but also qualities like optical symmetry. Getting a diamond with consistent hearts and arrows is a good way to ensure you have that, but it’s smart to post the ASETs and have get some feedback as not every vendor has the same standards for hearts and arrows.
The PS recommended angles are typically as follows:
Table : 54 - 58
Depth : 60 - 62.3
Crown : 34 - 35
Pavillion: 40.6 - 40.9

Note.... with a shallow Crown Angle like 34 you want to pair that with a Pavillion Angle like 40.8 to 40.9 and vice versa a Crown with 35 you pair that with a Pavillion of 40.6
These angles are complimentary.

Keep in mind the angles on a GIA cert are averages from the diamonds measurements (remember, it’s a 3D object) which is part of the reason ideal scopes and ASETs are so important in making an informed selection.

I’d try looking on websites of HPD, WF, VC and BG for their super ideal explanations.
